567 ACUS03 KWNS 081909 SWODY3 SPC AC 081908 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0108 PM CST Fri Nov 08 2024 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not expected on Sunday or Sunday night. ...Synopsis... The mid/upper cyclone over the Upper Midwest will shift east/northeast into southern Quebec and the Northeast. A quasi-stationary surface boundary will extend southwest from a Great Lakes/southeastern Canada low into the Mid-South and east Texas. Isolated thunderstorms will be possible within the warm sector ahead of the front. Poor lapse rates, weak instability and weakening vertical shear will preclude severe thunderstorm potential. A few thunderstorms may develop near the Pacific Northwest coast late Sunday/early Monday as a shortwave upper trough approaches the region. Additional thunderstorms also are possible across south FL from late afternoon onward as moisture increases within a southeasterly flow regime. ...Coastal Louisiana... Forecast guidance continues to show some spread regarding the central position of Rafael on Sunday. However, ECMWF ensembles mostly still align with latest track guidance from the National Hurricane Center, keeping the low well offshore the Gulf Coast. As such, tornado potential is expected to remain low. ..Leitman.. 11/08/2024 $$
